Install MongoDB on Ubuntu 16.x or Centos 7.x

MongoDB is a document-oriented database management system that can be distributed over any number of computers and does not require a predefined data schema. It is written in C++. The server and tools are distributed under the AGPL license (Is a free copyleft license, intended to oblige the services accessible by the network to publish their source code).
Prerequisites
Ubuntu 16.04 or Centos 7.x server set up by following this initial server setup tutorial, including a sudo non-root user.Add the MongoDB Repository
You have to import their key for the official MongoDB repository.sudo apt-key adv --keyserver hkp://keyserver.ubuntu.com:80 --recv EA312927
Output
gpg: Total number processed: 1
gpg: imported: 1 (RSA: 1)
Create a list file for MongoDB.
echo "deb http://repo.mongodb.org/apt/ubuntu xenial/mongodb-org/3.2 multiverse" | sudo tee /etc/apt/sources.list.d/mongodb-org-3.2.listUpdate the packages list.
sudo apt-get update
Installing and Verifying MongoDB
sudo apt-get install -y mongodb-orgCreate a unit file to manage the MongoDB service. Create a configuration file named
mongodb.service
in the /etc/systemd/system
directory using nano
or your favorite text editor.
sudo nano /etc/systemd/system/mongodb.serviceCopy/Paste in the following contents, then save and close the file.
/etc/systemd/system/mongodb.service
[Unit]
Description=High-performance, schema-free document-oriented database
After=network.target
[Service]
User=mongodb
ExecStart=/usr/bin/mongod --quiet --config /etc/mongod.conf
[Install]
WantedBy=multi-user.target
- The Unit section contains the overview (e.g. a human-readable description for MongoDB service) as well as dependencies.
- The Service section how the service should be started.
- The last section, Install, tells
systemd
when the service should be automatically started. Themulti-user.target
is a standard system startup sequence, which means the server will be automatically started during boot.
sudo systemctl start mongodbUse
systemctl
to check that the service has started properly.
sudo systemctl status mongodb
Output

Enable automatically starting MongoDB when the system starts.
sudo systemctl enable mongodb
Adjusting the Firewall (Optional)
Assuming you have followed the initial server setup tutorial instructions to enable the firewall on your server, MongoDB server will be inaccessible from the internet. Allow access to MongoDB on its default port27017
from everywhere:
sudo ufw allow from your_other_server_ip/32 to any port 27017Check the change in firewall settings with
ufw
.
sudo ufw status
